Re: catalina27-talk: Batteries

[Rspeers]

We use a solar panel to keep  the batteries charged. They are relatively inexpensive, last forever (unlike batteries), no electrolysis, no cable to attach to the shore, etc.   To estimate the size of solar panel to use, multiply the number of hours your use the batteries times the current drawn, multiply by two and divide by the number of sun hours between the times that you use the batteries. The factor of two is for the solar angle on the panels. If you have the money, double the estimate.   Bob
